Since FreeCAD interface is based on the modern Qt toolkit, it has a state-of-the-art organization. Widgets, menus, toolbars and other tools can be modified, moved, shared between workbenches, keyboard shortcuts can be set, modified, and macros can be recorded and played. The customization window is accessed from the Tools -> Customize menu:
The Commands tab lets you browse all available FreeCAD commands, organized by their category.
In Keyboard, you can see the keyboard shortcuts associated with every FreeCAD command, and if you want, modify or assign new shortcut to any command. This is where to come if you use a particular workbench often, and would like to speed up its use by using the keyboard.
The Toolbars and Toolbox bars tabs let you modify existing toolbars, or create your own custom toolbars.
The Macros tab lets you manage your saved Macros.
Create your Toolbars for your macro Customize Toolbars
In 0.16 version is available a new tool that lets you manage your workbenches
For an example workflow lets suppose we want to have the "Measure Linear" tool also show up in a custom toolbar in draft workbench.
